You could use

grep( !/$re/, @array )
[download]

grep( $_ !~ $re, @array )
[download]

What about something within the regex itself?

/$re/
[download]

is effectively short for

/\G(?s:.*?)$re/
[download]

This is a form we can negate.

/\G(?!(?s:.*?)$re)/
[download]

So you could use

grep( /\G(?!(?s:.*?)$re)/, @array )
[download]
